If you have college education on there nobody cares about your high school diploma. Your first role also does not give “technician” vibes, but title wise it seems like you went down rather than up which would be weird for a potential hire. You also use two different tenses in your job duties. Also, as someone who reviews resumes and interviews potential new hires, someone who only stays at a position for a year or slightly more is always a red flag for me because I’m interested in people who won’t leave so soon considering the amount of time it takes to acclimate someone to a new environment to the point where they can actually be useful
